NAME

  AsconfWithDelExists.seq - ASCONF chunk is received with Delete IP Address Parameter which contain a address part of the association


PURPOSE

  To check that if ASCONF chunk is received with Delete IP Address Parameter
  which contain a address part of the association then the endpoint should
  removed the address specified from the existing association.


SYNOPSIS

  ./AsconfWithDelExists.seq [-tooloption ...] -pkt ./AsconfWithDelExists.def
    -tooloption : v6eval tool option

PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange the date
  in endpoint A such that ASCONF chunk with Delete IP Address Parameter
  which contain a address part of the association is sent to endpoint B.


TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)
  ASCONF        ----------------->
  (Delete IP Address)
                <-----------------      ASCONF-ACK
                                        (Success)
  TEST DESCRIPTION:
  1. Send ASCONF chunk from endpoint A to B with Delete IP Address Parameter
     which contain a address part of the association.
  2. Check A: ASCONF-ACK with complete success should be received at endpoint
     A and the address specified is to be removed from the existing association
     at endpoint B.


NOTE

  None

    ASCONF-Request Correlation ID: 32 bits
    This is an opaque integer assigned by the sender to identify each
    request parameter.  The receiver of the ASCONF Chunk will copy this
    32-bit value into the ASCONF Response Correlation ID field of the
    ASCONF-ACK response parameter.  The sender of the ASCONF can use this
    same value in the ASCONF-ACK to find which request the response is
    for.  Note that the receiver MUST NOT change this 32-bit value.
    Address Parameter: TLV
    This field contains an IPv4 or IPv6 address parameter, as described
    in Section 3.3.2.1 of [RFC4960].  The complete TLV is wrapped within
    this parameter.  It informs the receiver that the address specified
    is to be removed from the existing association.  This parameter MUST
    NOT contain a broadcast or multicast address.  If the address 0.0.0.0
    or ::0 is provided, all addresses of the peer except the source
    address of the packet MUST be deleted.
